8 Claims. (01. 114-117) This invention relates to a latch for doors, and The door or hatch cover is carried on hinges particularly for bulkhead doors or hatch covers. l3 and provided with handles I4 so that thedoor The object of closure members of this type is may beopened or closed. The gasket 9 which is to provide means to force a door or hatch cover continuous around the entire structure, is adapt= into sealing contact with the frame or other ed to be forced against a flange l5 formed on the member surrounding the door. Where closure deck or on the bulkhead, in the case of a bulkmembers are attached to bulkhead doors by seamhead door. The flange I5 is provided at intervals welding there is a tendency to cause warping or with recessed keeper plates IE to receive the latch distortion of the panels of the door. Where of the securing member hereinafter described. '10 screw threads are used it is diflicult to maintain All of the parts heretofore described are shown 10 a tight joint. It is necessary both to prevent in the co-pending application of Joseph J. Masdistortion and insure a tight joint. Therefore, cuch and Alexis S. Gorshkoff, SerialNo. 2,152, the object of this invention is to provide a closure filed January 1'7, 1935, and form no part of the member which may be applied to a door or hatch present invention. cover without use of welds or threads. The closure member is applied near the edges 15 A further object of the invention is to provide of the panels 3. The closure member is applied a simple device which will withstand wear and to the panels 3 and strips 5 before the application hard usage, and which may be readily applied thereto of the sealing angle 6, and the parts carto doors made up of a plurality of spaced panels. ried thereby. In this way the spacer ring, here- The invention consists of the construction, inafter described, may be inserted between the 20 combination and arrangement of parts, as herepanels 3 from the edge thereof. In order to apply in illustrated, described and claimed. the closure member a suitable hole is formed In the accompanying drawing, forming part through the panels 3 and the re-inforcements 4 hereof, is illustrated one form of embodiment of and 5. A spacer ring I1 having a chamfered inthe invention, in which drawing similar reference ner edge I8 is disposed between the panels 3 in characters designate correspondingparts, and in alignment with the opening provided for the clowhich the invention is shown as being applied to sure member. The spacer ring l1 may be chana hatch cover. Hatch covers are normally used neled as shown at 19 to reduce the weight, and in a horizontal plane and it will be obvious that the ring I! may be temporarily held in position the invention may be app d q y W o a by a single spot-weld. The weld, however, is used door used in a verticalplane. It will also be clear merely to prevent movement of the ring I! durthat the closure member may be applied to the ing assembly, and is not sufficient to cause any bulkhead or deck adjacent the door, instead of distortion of the panels 3.

Referring to the drawing, thedoor is made up abuts the inner edges 20 of the strips 5 which of a plurality of panels 3 which are separated by have been pressed, as above described. The a corrugated, re-enforcing spacing member 4. upper end of the sleeve 2| is provided with a Adjacent the edges of ,the panels 3 are disposed reduced neck 23 adapted to be distorted, as 45 re-inforcing strips 5.

A re-inforcing angle 1 may be used lower edge 25 is applied over the upper part of to secure the angle member 6 to the'lower panel the sleeve 2|. The collar 24 is provided on its 3. Secured at the edge of the upper panel 3 is upper edge with an inturned lip 26 adapted to 50 a channel member 8 which holds in place a conlie against the reduced neck 23 of the sleeve 2|.

tlnuous gasket 9 with the aid of a gasket retainer The work is again placed in a press and the neck "I. All of the members thus far described are 23 is turned outward over the upper edge of the formed into a homogeneous entirety by means collar 24. In this way the parts are permanently of numerous spot-welds II or seam-welds l2. sealed together and a much stronger and more 55 by screw-threads. At the same time, there is no distortion possible, since there is no welding and the ring I! prevents any collapse of the panels 3.

A spindle 21 is rotatably disposed in the sleeve 2| and is provided with an operating handle 28 on one end and a squared end 29 on the opposite extremity. Suitable gaskets 30 may be applied around the spindle 21 adjacent the upper and lower ends of the sleeve 2!. A lower handle 3| is disposed on the lower end of the spindle 21 and is held in position by a nut 32. The handle 3| has formed thereon a projecting latch 33 formed with an inclined face 34 adapted to ride against a correspondingly inclined face in the keeper plate I6. When either handle 28 or 3| is rotated to force the latch 33 into the keeper plate l6, the inclined face 34 will cause the gasket 9 to be forced against the flange to form a liquid proof seal around the entire door or hatch cover.

Between the sleeve 2| and the spindle 21 may be disposed a bushing 35 provided with open spaces 36 into which may be introduced a semisolid lubricant or a packing impregnated with a lubricant. Oil slots 3! maybe formed on the inner face of the sleeve 21 to provide for lubrication. The oil slots 31 may be independent from one another, or may be a single slot formed as a spiral, the object of either form. being to provide space for the retention of a lubricant.
